Abstract Ignatowski (1910) showed that assumptions about light are not necessary to obtain Lorentzian kinematics as one of only few possibilities. We give a much simplified proof of his result as formulated by Gorini (1971) for n +1-dimensional space–time.

没有光的相对论：伊格纳托夫斯基定理的新证明

摘要 Ignatowski (1910) 表明关于光的假设对于获得洛伦兹运动学作为仅有的少数可能性之一不是必要的。我们对 Gorini (1971) 对 n +1 维时空的结果给出了一个非常简单的证明。
